Specification of Letters Patent.

Patented Get. 29, 1918 Application filed October 15, 1917. Serial No. 196,646.

To all whom it may concern:

Be it known that I, DANIEL A. HOPPING, a citizen of the United States, residin at Sturgis, countyof St. Joseph, State of ichigan, have invented certain new and useful Improvements in Book-'Making Machines, of which thefollowingis a specification.

This invention relates to improvements in book making machines.

My improvements are especially designed byme forapplying covers tosales books and the like, althoughthey are adapted and desirable foruse in applying covers to tablets I and other books or pads.

The main objects of this invention are:

First, to provide a machine for applying covers to sales books and the like which is automatic in, its operation and of large capacity.

Second, to provide a machine having the above recited advantages-which is comparatively simple and economical in structure and durable in use.

Third, to provide an improved machine having these advantages requiring but'little attention on the part oftheoperator.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of-my invention by the devices andmeans described inthe following specification. The invention is clearly defined and pointed out in the claims;

A structure which is a preferredembodiment of'my inv' en-tion isclearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Fig. XIV is alongitudinal section through one of the completed books.

' In. the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows atthe ends of the section lines.

Referring to the drawing, 1 represents the stapler which is supported by a suitable pedestal 2. As the details of the stapler and driving means therefor form no part of this invention they are not illustrated or described herein.

The stapler pedestal is preferably utilized as a support for one end of the frame, designated generally by the numeral 3. The

other end of the frame is supported by legs or standards I.

At the ends of the frame I mount the sprocket wheels 5 and 6 for the conveyer chains 7. The upper reaches of the conveyer chains travel on ways 7 These con- *veyer chains are provided with cross pieces 8 on which are mounted coacting pairs of flights 9 and 10 forming pockets adapted to receive the covers and sheets, as will be hereafter described.

The forward flight 10 of each pair is provided with a rearward extension 11 which assists in discharging the stapled books from the conveyer, as will hereafter be described.

The driving shaft 12 is connected by the sprocket wheel and chain 14 to the driving mechanism of the stapler, not here illus trated. On this shaft 12 is a crank disk 15 connected by the pitman 16 to the pawlcarrying rocker 17 which is pivoted on the shaft 18 and provided with a pawl 19 coacting with the ratchet wheel 20. The shaft 18 is provided with a sprocket wheel 21 connected by the sprocket chain 22 with the sprocket wheel 23 on the shaft 24 of the conveyer sprocket wheels 5. This ratchet mechanism drives the conveyer with a stepby-step movement which is timed with the stapler. A tension idler 25 is provided for the chain 22.

The covers are placed in a hopper 26 disposed at the front end of the conveyer. The covers are fed to the conveyer by the reciprocating feed member 27. This feed member is connected by the link 28 to an arm 29 on the rock shaft 30. This rock shaft is provided with an arm 31 connected by the link 32 to the lever 33 pivoted at 34 and slotted at .35 to receive the crank pin 36 on the crank 37. This crank 37 is on a shaft 38 provided with a sprocket wheel 39 connected by the sprocket chain 40 to a sprocket wheel 41 on the driving shaft 12.

The actuation of the cover feed slide is timed so that the covers are delivered into the conveyer pockets. However, the covers are not ejected from the hopper until the front flights 10 are substantially at the top of the front conveyer sprocket wheels.

Mounted on the shaft 42 of the front conveyer sprocket wheels 6 and at the outer sides thereof are friction feed rollers 43 adapted to engage the covers when ejected by the feed member and carry them along until they are positively engaged by the rear flights or pocket members. Pressure feed rollers 44 carried by the fixed arms 45 are supported above the rollers 43 so that they hold the covers in effective frictional engagement therewith and insure their being fed into the pockets.

The covers 46 are scored previous to placing in the hopper along the dotted lines 47 and 48 to facilitate folding. The dotted lines 47 are the binding flap folding scores, and the lines 48 the cover extension or closing flap scores. In practice, the covers are printed and scored at the same operation. As the covers are carried along by the conveyer their binding flaps 47 are carried below the fixed flap turning member 49 which is, in the structure illustrated, yoke-shaped in cross-section, its outer arm being mounted on the vertical gulde 50,see Fig. VIII.

While the covers are positloned under this fixed flap turning member the binding flaps are engaged by the reciprocating flap turner 51. The flap turner 51 is supported in brackets 52 and actuated by a lever 53 pivoted at 54 on the arm 55 extending from the frame. This lever is actuated by a tappet 56 on the crank 37. A coiled spring 57 is connected with the opposite end of the lever to return the flap holder to its initial position when released by the tappet. This provides a quick actuation for the reciprocating flap turner.

As the covers are carried along they pass under the pad hopper 58 with their upturned binding flaps against the guide and abutment 59. In this position one of the Pads or bundles of sheets 60 is ejected by the feed slide 61 under the pressure member 62 with the binding edge of the pad against the binding flap, as clearly shown in Fig. IX.

The feed member 61 reciprocates in ways 63. As the covers are carried along by the conveyer their closing flap extensions 48 are supported by the flat wa 64. A strip 65 is disposed at'the side 0 the conveyer so that the cover extensions slide along under the strip which prevents their being displaced from the conveyer pockets as they are carried along and operated upon by the binding flap turner. The cover extensions 48 pass below the feed member 61 and to effectively guide them below the same a guide 65 is disposed at the front side of the hopper. A guide 66 projects from the hopper under the pressure member 62 preventing the uptilting of the sheets as they are discharged from the hopper between the flights and upon the'covers.

The sheets are preferably stapled in pads, a suitable machine for the purpose being shown in my copending application for Letters Patent, Serial No. 196,415, filed Oct. 13,

1917. As the covers with pads therein are,

advanced from this position the cover extensions are engaged by the flap turner 67 and swung to a position in front of the cover extension folder 68, which is mounted on the reciprocating plunger rod 69 carried by the support 70 on the shelf-like frame extension 71. This plunger rod 69 is returned to its initial position by the spring 72 arranged thereon, as shown in Fig. IX.

The plunger 69 is operated by the arm 73 on-the rock shaft 74, the rock shaft being provided with a second arm 75'projecting into the path of the tappet 76 on the link 77 constituting a part of the actuating connections for the feed slide 61. This link 77 is mounted on the lever 78 pivoted at 7 9 and connected by the link 80 to the cam actuated slide 81. The slide 81 is actuated by the cam 82 on the shaft 39,--see Fig. IX. The driving connections for this shaft have been described. The flap turner 67 is extended rearwardly and constitutes an abutment for therewith, as shown in Fig. V.

nasegssa;

under a clamping means comprising cross bars83 mounted on sprocket chains 84 supported by sprocket wheels 85 arranged so lo that the lower reaches of the chains travel in a plane parallel to the upper reach of the conveyer and in a spaced relation thereto, so that the cross pieces engage the pads with the covers folded thereon and travel along The shaft 86 of one of the sprocket wheels is connected by the sprocket chain 87 and suitable sprocket wheels to a shaft 88 which is provided with a sprocket wheel 89 driven by one of the conveyer chains 7 The shafts of the sprocket Wheels 85 are connected by the sprocket chain 85 and suitable sprocket wheels.

- As a'pad is carried along, the upstanding -1 binding flap is engaged and turned by the flap turner 90 and carried under it and held in folded position until the staples are inserted. The completed books are discharged as the flights pass over the rear conveyer 80 sprocket 5, the extensions 11 of the flights being adapted to tilt the books from the conveyer pockets so that they are deposited in the rack 91. To prevent the cover extensions swinging open when the books are discharged I- provide a curved arm 92 which projects rearwardly over the rear conveyer sprocket wheels. The finished books may be lifted from the rack in bundles ready for packing.

I havedescribed the various mechanisms and operations practically in the order of operation, but in the interests of clearness will-point out the general cycle of operations. The stapling mechanism is automatic m its operation and the conveyer is timed to the operation thereof. Ordinarily all that is required of the operator is to keep the coverand, sheet hoppers filled and remove the stapled books.

Covers are discharged from the hopper one by one and delivered into the conveyer pockets by the reciprocating feed member and the feed rollers. As the coversare carried along by the conveyer the binding flap es -us turnednpwardly by the binding flap turners 49 and 5l after which they are carried below the pad hopper and the pads ejected thereon with their binding edges abutting the upstandingbinding flaps. As they are (m further carried along, the cover extenslons are turned up by the extension turner 67 and engaged by the extension folder 68 which folds the extension flaps down upon the sheets. The binding flap is-engaged by the ea flap turner 90 and turned down upon the sheets in position to receive the staples. The books with folded covers are then engaged by the movable guide means described and are clamped thereby during the stapling operation and while they are advanced to the discharge.

By my improved mechanism I am able to manufacture books of the class described rapidly and uniformly and without distortion of the sheets.

I have illustrated and described my improvements in an embodiment which I have found entirely practical. I have not attempted to illustrate or describe certain modifications in structural details which I contemplate and which might be desirable for certain adaptations, as I believe the dis closure made will enable those skilled in this art to embody or adapt the same as may be desired.
